Gu Cheng is an ordinary clerk at the "Time Grocery Store". He has a taciturn personality and is accustomed to using smiles instead of words. He owns a golden pocket watch that can fine-tune the status of items. This is his only golden finger and his secret weapon to heal his life. However, one day, the pocket watch suddenly went out of control, and the items in the store began to act on their own: the broomstick started to tap dance, the teacup chased the customers, and even the old-fashioned radio sang rock and roll. To make matters worse, Su Qianqian, the new female neighbor who moved next door, is gentle and considerate on the surface, but is actually a top-notch "green tea". She takes advantage of Gu Cheng's weakness of not being good at words, and tries to seize the pocket watch and control the city step by step. In the daily life of chaos and conspiracy, Gu Cheng was forced to speak, using a clumsy but sincere way to repair the out-of-control items bit by bit and melt the ice of people's hearts bit by bit. This is a light novel about how the silent ones use their quietest power to heal the world and themselves.
